59 the guide for the feed bed. 1 in place... A pair of-adjusting screws1221 serve to control by fine adjustment the height of frame bar 11, v

The clamp frame 13 adjusts up and down on the face of the frame bar 11.This is accomplished for clamping purposes by a pair of cams 14, seeFigs. 1, 3 and 9, the cams being provided with lever arms 141 which areconnected by the link 1142 which is knurled to serve as a handle, sothat the cams are operated simultaneously and quickly. These cams forcethe clamp frame 13 down. The clamp on its face is provided with a seriesof clamping rollers 15 which are journaled in suitable spring pressedblocks 151 which play up and down in guide slots 131 in the clamp 13. herolls are held yieldingly downwardby the springs 152 on shanks 153 whichshanks reciprocate in suitable openings in the said clamp frame 13.

A presser top feed means cooperates with the feed bed opposite thecutter head and receives the clamped veneers. This presser feed conveyorcomprises a frame bar 16. r This is provided with a plurality of springpressed rollers 17, compar ble in all details with. rolls 15, whichcooperate with the said feed bed. Around these rollers 1'? is disposedan endless belt 18 which insures the operation of the feed rolls afterthe engagement by them of the advancing end of the clamped Veneers. Theframe ba 16 is can ried on uprights 12 exactly like uprights 12 andframe 16 is made adjustable by means identical with the means thatadjust frame bar 11.

A yielding guide 19, see Fig. 5, is pressed laterally by springs 191 andengages the links of the feed bed. Guide 192 on the 0pposite side isadjustable by set screws 193, 194, see Figs. 2 and 6. By adjusting thisguide 192 so that it delivers the bed in a slightly curved path to theplaner head, what is known as a hollow joint is produced. That is ajoint in which the ends of the veneerstrips press slightly in advance ofthe center part, which insures a tight oint for the entire length of theveneer.

20 is a work guide that extends from th clamp section to the feedsection terminating near the cutter-head. The work guide 20 iscontrolled by a pair of racks 201 connected thereto which are acted uponby'a pair of segment gears or pinions 202, see dotted'lines in Fig. 4.These are controlled by the lever 203 on rockshaft 204 on which the saidsegment gears 201, 202 aremounted. A scale 205 is provided for theadjustment of the said lever 203 which is clamped by set screw 206 tothe slotted segment bar 207, see Fig. 4. The amount of cut thus be veryclosely regulated.

The links of the feed bed conveyor are lubricated by providing anadjustable spring guide slide with felt pads saturated with lubricant,see Figs. 7 and 8. This lubricator.

is a guide and consists of a back 21 with hinged side wings 22 heldyieldinglyin place by springs 23, see Fig. 7. Felts 24 and 25, 25 forcarrying lubricant are carried by the back and sides. These are providedwith perforated faces 241, 251, 251 of sole leather to resist wear andpermit through lubrication.

in operation with the machine running, a number of layers of veneer, seeFigs. 3 and 5, are placed on the yielding table with their edgesprojecting over the feed bed against the veneer guide. The clamp 13 isforced down onto the same by the actuation of the cams 14. The veneers,directed by the guide 20 are then carried by the feed bed from under theclamp, owing to the revolving of the rollers 15 of the said clamp to thepresser feed roller section, where as soon as the veneers are engagedthey are advanced, because of the presence of the belt 18 around thesaid feed rollers. The feed bed being controlled by the guide 192, itcarries the clamped and retained veneers past the cutterhead- Owing tothe slight deflection of the feed bed, the planer forms what is known asa hollow joint.

l v hcn one edge of a bunch of veneers has been planed and jointed, theguide 20 is withdrawn. The veneers can then be clamped separately in apile together and ad justedfin the machine according to the scale of thetable 9 and the opposite edge uniformly planed and ointed. Thusidentical veneer strips can be produced.

The structure of my machine can be varied by providing driven feedrollers and a chain feed for the final half of the machine as seen inFig. 9. 1 show in Fig. 9 an endless feed carrier 24 driven by a pulley25 which pulls the carrier past feed rollers that are comparable tothose appearing in the principal View, Figs. 1 and 3.

l desire to claim the invention broadly and also the two species that Ihave illustrated specifically, as pointed out in the appended claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:
